Step 1 Before you start with Multi-Tool

This chapter shows a brief description of the wizard. Please note that the screenshots are illustrative and might differ from those in the firmware.

Make sure you are running Firmware 5.1.2 or newer

You can download firmware updates HERE. Guide for updating the firmware is HERE

Some parts of the wizard must be done multiple times, this depends on the number of tool-heads. For example:

⬢Dock Calibration

⬢Loadcell calibration

⬢Filament sensor calibration

Step 2 Preparing the printer

Make sure that the printer is placed in a stable place where no ambient vibrations are transmitted (for example, where other printers are printing).

⬢From the rear side of the printer, plug in the PSU cable.

⬢Turn the power switch ON (symbol "I").

Step 3 Prusa Nextruder sock (Optional)

⬢A silicone sock is supplied with each Nextruder package.

⬢If you want to install the sock, do it before the calibration.

How to install the sock - check the article.

Step 4 Nozzle seal height calibration

Starting from May 2024, you may receive a gray nozzle seal. The assembly and functionality remain identical to the red one.

⬢The following image was made with the Nextruder and dock removed from the printer for better visibility of how it should be set. Please do not remove the docks from the printer and set the seal height with the dock still connected to the printer.

⬢In the next step, we'll calibrate the height of the nozzle seal.

⬢Using the 2.5 mm Allen key, tighten or untighten the M3x30 screw to calibrate the height of the nozzle seal.

⬢Proceed to the next step.

Step 5 Nozzle seal height calibration

⬢If is the Nozzle seal too low or too high, we need to reposition its height.

⬢Using a 2.5 mm Allen key:

⬢Turn the M3x30 screw clockwise to set the Nozzle seal lower.

⬢Turn the M3x30 screw counterclockwise to set the Nozzle seal higher.

⬢The correct position of the Nozzle seal is, that the Nozzle seal isn't bent and it is touching the nozzle.

Step 6 Wizard

⬢After the printer starts up, the screen prompts for the printer test and setup wizard.

The wizard will test all important components of the printer. The whole process takes a few minutes. Some parts of the wizard require direct user interaction. Follow the instruction on the screen.

NOTE: While testing the axes, make sure that there is nothing in the printer that is obstructing the movement of the axes.

WARNING: Do not touch the printer during the wizard unless prompted! Some parts of the printer may be HOT and moving at high speed.

Step 7 Wizard: Dock Position Calibration

⬢You will need:

⬢Universal wrench (1x)

⬢Mini wrench (1x)

⬢Dock calibration will guide you through how to properly calibrate the position of individual tool heads on the printer.

It is necessary to follow every step in the dock calibration properly! Do not rush, read every step twice, then proceed with the instruction.

Step 8 Wizard: Loosen pin

⬢Follow the wizard instructions on the screen.

⬢Using a Mini wrench, loosen and remove both dock pins on Dock 1.

Step 9 Wizard: Loosen screws

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, loosen two screws. A few turns are enough.

Step 10 Wizard: Lock the tool

⬢Follow the wizard instructions on the screen.

⬢Manually move the Tool changing mechanism to the first tool.

⬢Manually lock the metal bars as described in the picture.

The tool has to be locked in the tool changer.

Step 11 Wizard: Tighten the upper screw

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, tighten the upper screw on a side of the dock.

After confirming by the continue button on the LCD, the XY axis will leave the dock with the tool. Clear the space.

Step 12 Wizard: Tighten the lower screw

⬢Follow the wizard instructions on the screen.

⬢Using a Uni wrench, tighten the lower screw on a side of the dock.

Step 13 Wizard: Install pins

⬢Follow the wizard instructions on the screen.

⬢Insert the two metal pins and tighten them with a Mini wrench.

⬢After clicking on the continue button on the LCD, the printer will put back the tool into the dock1 and do a few calibration moves.

⬢After the Dock1 calibration, proceed to the Dock2 calibration and repeat the steps.

Step 14 Wizard: Dock successfully calibrated

⬢Good job! The Dock1 is calibrated.

⬢According to the number of print heads, the dock calibration process is repeated.

Step 15 Wizard: Test Loadcell

⬢The next step of the wizard will prompt you to touch the nozzle to test and calibrate the Loadcell. During this procedure, the parts of the printer are not heated, you can touch the parts of the printer. Click on Continue.

⬢Do not touch the nozzle yet, wait until prompted with the message: Tap the nozzle NOW.

⬢Slightly tap the nozzle. No need to use extra force. In case the Loadcell does not detect enough touch, you will be prompted to repeat the step. Otherwise, you will see Loadcell test passed OK when it succeeds.

Step 16 Nozzle diameter confirmation

⬢In the next step of the wizard, the printer will ask you for the diameter of your nozzle.

⬢Count the marking (dots) on your nozzle in the Nextruder.

⬢Select the option:

⬢3 dots - 0.40 mm nozzle

⬢4 dots - 0.60 mm nozzle

Note that if you change the nozzle diameter, you will need to change the settings on the printer.

Step 17 Wizard: Calibrate Filament Sensors

⬢During the calibration of the filament sensors, you will be prompted to use at least 130 cm of filament. Hint: Use the Prusament shipped with your printer and hang it directly on the spool holder.

⬢When you have prepared the filament, click on YES.

⬢Wait for the printer to prompt you to insert the filament into the side filament sensor.

Step 18 Wizard: Calibrate Filament Sensors

⬢Now, insert the filament into the side filament sensor and push it until it reaches the filament sensor in the extruder (you will feel a slight resistance).

⬢You can check the side filament sensor (left) and extruder filament sensor (right) status on the bottom bar on the screen.

⬢Both filament sensors are successfully calibrated and tested. Click on CONTINUE.

According to the number of print heads, the filament sensor calibration is repeated.

Step 26 Semi-Assembled version only - Checking the Heatbed installation

In this step, we will make sure the Heatbed is installed correctly

⬢Using the T10 screwdriver, slightly loosen all screws on the sides of the bed-frame. A few turns are enough.

⬢Visit the menu Control > Move Axis and adjust the Move Z value to the lowest position.

⬢Leave the heatbed for a few seconds until it settles in the lowest position.

⬢While in the lowest position, tighten all screws using the T10 screwdriver.

Step 27 It's done

⬢That's all, the printer is ready to print. But still, follow the instructions in this manual to the end.

Step 28 Regular printer maintenance

To keep your printer working properly over time, it is highly recommended to do regular maintenance.

⬢For regular printer maintenance, follow the Regular printer maintenance (XL) article for information and instructions.

On multi-tool printers, it is necessary to focus on lubricating the coupler pins of the ToolHeads.

Lubricating the coupler pins can be made along with the rest of the maintenance, or it can also be done if you notice that your prints have banding or ringing issues.

⬢To lubricate the coupler pins use our dedicated online guide How to lubricate the coupler pins on Original Prusa XL.

You will need to print an applicator to lubricate the pins. Please refer to the dedicated guide for more information.
